What is the maximum voltage supported by the PO3-640 mainboard for the RAM?

Hi everyone. I have recently bought a Predator PO3-640 and now I'm thinking about upgrading the RAM. Specifically, I'm considering to buy two ‎KF432C16BB1AK2/32 (Kingstone Fury Beast RGB DDR4 RAM 3200MHz CL16 16GB) and I would like to know if they are compatible. My issue is if the mainboard could support them given that I read that the RAM modules use a 1.35v voltage and the one mounted on the PC at the moment is 1.2v.

Moreover I'll appreciate to understand if the mainboard support dual-four rank, beacuse I've not understood it form the User Manual. Thank you in advance and I'm sorry for possible grammatical errors.

Yes, you can use the Kingston Ram and the Ram will use 1.2V power.

Below is the upgrade for you Ram and also you can go through the below thread for more info

The PO3-640 supports DDR4-3200MHz CAS# Latency (CL) 22 (Target CL-nRCD-nRP - 22-22-22) 1.2V only type ram, you can't fit CL16 type ram and/or mix different CLs ram as the ram will not work and your desktop won't boot. The Acer suggested and compatible 16GB ram is listed below for all compatible 16GB DDR4-3200MHz modules, so stick to these modules and install them appropriately and like in the PO3-640 Manual into DIMMs 1 and the max 64GB capacity at 4x 16GB DDR4-3200MHz CL22 only ram.

I know I cannot mix different RAMs, but I've read on every forum that respecting frequency and type, every CL will work. For this reason I thought that two of this RAMs will work. However, thank for the answer!
